The aim of the present report is to describe the
morphology of Class II division 2 malocclusion
based on a cephalometric comparison of a group of
48 individuals (Björk). Results demonstrate a clear
increase in the sagittal jaw relationship related
to a retrognathic mandible, which demonstrates
morphology indicative of an anterior rotational
growth pattern. In the vertical plane, a skeletal deep
bite was seen though the distribution of this anomaly
was seen to be dichotomous suggesting that two
morphologically different groups could be identified.
The role of perioral musculature in the development
of the retroclined incisors (maxillary and mandibular)
was discussed. As an addendum to the main report a
differentiated treatment protocol relating particularly
to the vertical jaw relationship was presented and
discussed.
